Cold (mid 20's) and clear the last two nights with very little wind. I got an insulated thermos mug from Eleven Gear for Christmas and I love it. It is nice to have a hot sip of coffee or tea on these cold rides. Over the weekend I took it on a longer ride and it was still warm 90 minutes into the ride. I also ordered a "real" cycling winter jacket yesterday, should have it by the end of the week.
